INITIAL-HEAT LEER AND AUTOMATIC FEEDING EQUIPMENT.

Application led September 25, 1920. 4Serial No. 412,710.

To all lwhom t may concern:

Be it'known that I, VVILBURl S. MAYERS, a citizen of the United States, residing at Fairmont, in the county of Marion and State of West Virginia, have inventedl new and useful Improvements in Initial-Heat Leers and Automatic Feeding Equipment, `ofwhich the following is a specification.

My invention relates to annealing chambers and automatic feeders used in glass manufacturing plants forsuch articles asbottles, tumblers, packing jars and the like.

- ing 'to the vfact that there is an avoidance4 scribed.

Heretofore'the annealing of these articles hasbeen'done in furnaces and chambers requiring a large amount of fuel for reheatL ing the ware and several hours for the. operation.

In my device anew method is employed in the process of annealing and it differs from the old method in that the w'are is taken hot from the mold set as close as practicable to the leer and transferred to a heat insulated chamber in a space ofy time short. enough to prevent the cooling of the Ware below a certain critical temperature at whichannealing is impossible without reheating. In the leers in pres-ent use, including both Athe automatic and hand-fed types, the transfer .of the ware from the molds-to the heated chamber can not be accomplished in a Space of time sufficiently short to prevent the setting or partial solidiication of the thinner walls of the ware. Internal strains due to unequal contraction are thus produced and in orderA toy remove lthese strains the Ware must be again'raised toy a temperature at which the molecular structure may rearrange itself. When this transfer is made within a period offrom two to four seconds, dependingupon the thickness of the glass walls ofthe ware, it has beenl found possible to anneal the articles perfectlywithout the application of external heatand in much less time than by the old method. Furthermore better results are produced thanthose in leers now in use owof theinternal stresses in the glass walls due to to'o rapid cooling. As articles of pressed glassy emerge from the molds hot.`

enough to cohere -if brought into vContact with one another Within a `few seconds after their delivery such contacts must be avoided [du-ring this interval of time and this conditionis fully met in the device herein de- In the accompanying drawings, forming a part of this specification and in which similar characters of reference indicate like parts throughout the severalviews, Figure 1 is a vertical longitudinal section through the receiving chamber and transfer mechanism on the line 1 1 of Fig, 3. Fig. 2 is a horizontal section through the same parts on the line 2-2 of Fig. 3. Fig. 3 is an elevation of the receiving or front end of the leer. Figures la to 4c, inclusive, show-the elementary members of the mechanism for transferring the ware from the crossconveyor to the mainconveyor at different stages of the` operation in which it is understood that the numerical references in Fig. la apply also to like partsA Vin Figures 4b to 4e, inclusive. Fig. 5'is an enlarged diagrammatic side view of the car;- rier .operating cams showing their relative angular positions on their shaft and the location of points on their working faces corf responding ,to certainfpositions of the carrier parts as shown consecutively in Figures 4a Ato 4e, inclusiveLand Fig. 6 is a side elevation of the complete leer in broken`sections. Itis understood in this specification that 'the names of the various parts,` when given 'in plural and followed by a single charac-y ter of reference, .will indica-te. that such cov parts are-in pairs, one on-either side of the i' leer and transversely opposite to one another wand that they are similar in design and si-v multaneous in operation when referring to moving parts.

he receiving end of the leer and the-v transfer device 112 are placed intheir relative working positions and as close as is practicable to the delivery mold 8 of the pressing machine and in working relation therewith.

The mechanism of the transfer device and the leer feeding mechanism are`interconpected and are driven from a rotating part of the machine presswhich they serve, and

they are speeded and timed in fixed relation to the operating cycle and rate of production i vided always that each piece of ware is depositedin its proper place and in proper time relation to the leer parts. The use of the initial heat leer and `automatic feeding equipment herein described -is obviously `not restricted to the annealing of ware produced on pressing o-r blowing machines, and such articles as hand blown tumblers, glass chimneys and lamp shades-may also be included in the application of the device,

The main body of the leer, as shown in Fi 6, consists of the receiving and distri uting chamber 1 and the cooling sections 2 and 3. The main-conveyor` 4 is of the well known pan type and `is driven continuously by the `motor 5 through proper gearing at a speed in fixed relation to that of the feeding and distributing mechanism as hereinafter described. The walls of t'he receiving chamber 1 and thosev over the disk y transfer 9 are made of refractory and heat- -insulating materials of a thickness sufiicient to reduce the heat radiation to any desired extent. The walls of section 2, Fig. 6, have less heatinsulating properties than those of the chamber 1; those of `section 3 less than section 2, and so on, in any desired number I of sections, gradually reducing the insulating properties of the walls as the discharge endof the leerl is reached.

- N The vent flues 10, 1l\and dampers 12,

13 provide for more rapid cooling by. air

circulation when necessary or desirable.

The chamber 1 and cooling sections 2, 3

are just large enough to house the conveyors and the largest size of the ware to be annealed so that the radiating surfaces may be kept at the minimum.

With the exception of the annular ware passage way over the disk 9 the receiving end of the leer is entirely enclosed, which is a necessary condition for leers of this class.

A' small gas burner, not shown, may be casting located at orV near the entrance ofthe said annular passage under certain conditions or requirements` The bottom kmember of the conveyor-seal 14 extends continuously between the side walls. The top of the casting 14 just touches the under side of the'main-conveyor pans 4 and is rounded on the edge, as shown,

in order that' any warped pans may ride over it. In order to prevent cold air from entering t-he chamber fover the main-conveyor 4 `the top member of the seal 154is made to fit closely over thel conveyor pans and chains 31. Thisc-asting, extending between the side walls, has a small vertical travel and is loosely fitted under the rear end wall-of the chamber. It is prevented' f from -moving by friction with the mainconveyor@ bythe upward extending, ianges 16, 17, loosely engaging the bottom of the The'wall sections 19, 20 are'stationary but and is free to swing outwardly without undue-friction, asy shown in the dotted lines in Fig. 2. 'If from anycause. the ware should become clogged at the point of transf' when desirable." The cap 23 over the re-l ceiving chamber is hung on the hinges 24 so that it may be swung upward in order to permit free access to the chamber. The

eye-bolt 25 provides an attachment for lifting the cap on its hinges.

The combustion-chamber 26 is directly under the receiving-chamber and issepa rated therefrom by the baflieplate 27. ,This

plate fills the entire horizontal area of the chambers with the exception of the throat 28 and prevents the short-circuiting of the hot gases through the main-conveyorpans.

The lower run of the main-conveyor`-passes.

through the combustion-chamber` directly under the baffle plate in order that the chains and pans may be quickly and thoroughly pre-heated by the burners 29. These burners, two in number, are placed at the rear end of the combustion chamber and ldirectly Aunder the main-conveyor chains in order thatthke heavy masses of the chains may be in the hot part of the 'ame and therefore become more quickly brought tol an even temperature with the thin conveyorI pans., The gas mixers 30 are placed on the outside of the rear wall and connected to the burners by pipes extending through the wall and the casting 14.` Ignition ofthe gas is made through small. doors .near the burners.

The purpose of the burner-s fis primarily -to provide means for preheating the mainconveyor, cross-conveyor and carrier-plates as hot glassware is checked or cracked by contact with metal 'at a lower temperature.

They are urtheruseful as a means for making up the heat losses caused by unavoidable radiation from the chamber walls and for preheating the entire chamber and parts within after a shut-down. The heated products of `combustion pass through the throat 28 tor the top'of the -receiving-chamber yand then to the cooling chambers where they are carried f off by the lues 1 0, 112

Under r'unnlng conditions a'large amount of heat is given off by the lncomlng ware and ythe gas consumption must be so restricted that the temperatu-reof the receiving-'chamber will at no time be higher than that of the incoming ware, this temperature being preferablyabout`700 degrees F., which is muclrlower than that of hotware. Itis obvious that the dimensio s ofthe 65 the section 21 is hinged on the,pintle 22 chambers and the conveyors an carriers therein can be increased or diminished without in any way affecting the operation of the device or the method of its employment.

The disk vtransfer' `9 is rotatably mounted- .under the semicylindrical extension of'vthe front wall and inside the curved wall and in The annular channel between said Walls the `ware iscar'ried by the rotating disk tof theinterior of the chamber.

The two endless chains 31 run on the sprockets 32. These sprockets are keyed tol the shaft 3.3 which is journaled at the ends vto the bearings 34. T hesebearings are outside of the leer. chamber and are attached to horizontal extensions on the cast iron table 58. Similar sprockets are keyed to the shaft whichv is suitablyjournaled and is driven by the motor5 through'thev Gears 6, 7 and their intermeshin pinion and rm.

The upper or loaded run of the main# conveyor 4 is supported bythe angle guides 36 and the lower run upon similar guide 37. In the cross-conveyor the driven sprocket '.39 and driver sprocket 40 are' keyed to the which is farthest vert-icalshafts 41, 42 respectively. The endless chain 43 running upon these sprockets is supported by the guides 44 which are preferably in the form of an integral casting.

The chain is preferably of the roller type with offset links and has a pitch slightly greater than the diameter of they largest piece of ware to be carried by it.I From each upper link extends the attachment 45 Vand from each lowery link the attachment 4 5- Below the sprocket 40 is the fixed plate 46 whose top surface is in line with that of the transfer disk 9, the said plate and disk being closely adjacent but not touching one another. The plate conforms tothe circular path ofthe-chain attachments at this point vand terminates a short distance from the end of the carrier-plate 47. A

The carrier-plate, lying under the lower chain attachments 45 and over the main? conveyor, is so ,positioned that the pieces of ware carried l@ver the fixed-plate 46 vby the chain attachments will b'e carried. along in the samemamer over the said carrierplate. The outer. edfge .of` this plate, or that rom the chain' 43, is slightly' higher than the inner edge so` that 1n passing over j itthe bottles ortumblers will lean slightly towards the chain, as

sho-wn in Figures l and 4. .This inclination of the carrier-plate is just sufficient to cause the bottle or `other article to remain by lthe action of gravity close to the chain while -sliding over the plate. When the plate is advanced, however, in the manner fhereafter described, the inclination is not suilicient to cause the articles to slide thereon by gravity and they consequently follow the plate in'its advance movement.

rIfhe castiron carrier-levers 48 are rigidlyv attached at-.their inner ends toy the carrierlate and are fulcrumed on the pins 70 to 'the ower ends of theswinging-links 49, 49", 50 5()b which pass through slots in the plate 58.

These levers pass through openings in thel cast iron plate and frontwall just large enough to receive them without binding.

' They are in double section inside of the leer with the rollers 51, where the two/ arms or sections converge into the single sectlon as 'shown 1n Fig. 1.

`The outer ends of these levers bear up` ward, due to-their unbalanced` suspension, against the rollers' 51- which are journaled in the swinging ends of the rockerarms 52,

chamber and up to their point of contact 52h, 53, 53". These arms are keyed to the secondarymockereshaft 38 and the shaft is journaled in' t-hebearings 54.: l

The rider-plate 55 is rigidly attached tothe inner ends ofthe slides 56. These slides rest upon the shoes 57 and the latter rest slidably upo the cast iron table 58 which is rigidly bolted to the walls and to the iron` structure of the leer. The outer ends of the shoes have laterally projecting lugs which bear upon the rollers 59. These rollers have a travel equal to half the travel ofthe slides and reduce the friction between the shoes and the table 58. I

vThe slides 56 have a smalllongitudinal travel upon the/shoes for a purpose which will be`hereafter discribed. The inner ends `of the springs 60 are attached to the slides and the outer ends to the upward extending lugs `on the ends of saidshoe's, and their tension is adjustable by screws or other means;

The pins in the upper ends ofthe links 49, 49h, 50, 50b are tightly fitted in the links and loosely fitted in'holesv in the slides 56. The pins in the lower ends' of these links are tightly fitted in the double arms of the levers 48 and loosely fitted in thel links. `A The lo`wer holes in the links are ,elongated as shown in Figures 41'to 4* so that the levers may be slightly raised with the links stationary'. p

The stabilizer-arms 6l are hifurcated at their lower ends to receive the innerends of the shoes and slides and are fulcrumed to the shoes onv the pins 62. The pins 63 vfare tightly tted in the slides anduloosely in ,i the elongated holes in thestabilizerarms l forward travel of the slides and rider-platel upon the shoes 57 is limited by the length of the clearance spaces 67,7Figures 4, 4d, 4, between the eyes of the slides and the shoulders of the shoes. This forward travel of the `slides on the shoesY is sufficient to swing the stabilizer-arms inward and downwarda distance sufficient to bring the holder 64 intocontact with the ware at the beginning of the advance stroke of the carriers. v

The backward travel of the slides upon the shoes is limited by the upward projections 68, Figures 4b, 4. The rollers 69 reduce the friction between the` slides and their respective shoes.

The pins 70, passing through the carrierlevers and the swinging-links, as above described, pass also through the slots 71, Fig. 1, in the bearing brackets 72 `and are limited by the length of these slots in their forward and backward travel. Y

The inner ends of the connecting-links 73, 73", 74, 74", are pivoted at the central points in the swinging-links 49, 49, 50, 50, respectively and the outer ends of these connectinglinks are pivoted t'o the upper ends of the rocker-arms .75. These rocker-arms are keyed to the rocker-shaftl 76 which is jourroller 87 which runs on the face oft the cam 79. The arm 86 is pivoted to the eye 88 Vof the connecting-rod 89. The ends of theconnecting-rod are threaded right and left pivoted in the swinging end of the rockerarm 91 whose hub is keyed to the shaft 38.

. The cross-conveyor drive shaft 42 is keyed yto the spur gear 93 which meshes in the pinion 94. This pinion is keyed to the intermediate shaft 95 and lmeshes also in the spur gear -96 which is keyed to the hollow disk, shaft 113, Fig. 1. The bevel gear 97 is keyed Onthe'shaft 95 and meshes in the bevel pinion 98 which Ais keyed to the drive shaft 99. The drive shaft is connected to some rotative part of theI machine press and geared so as to have a certain speed ratio thereto so that the machine pressl and leer shafts will always be in correct time and speed relatonswith'one another.v

`The drive shaft 99 is also-keyed to the worm 100, and the wormv Wheel 101 is keyed piece of ware off of the plate 102 andthe bers, -are interconnected and firmly bolted on the cam shaft 80 so that'the cams are always in correct time and speed relations to the other parts of the feeding mechanism.

The stationary receiving-plate 102 is attached to the lfront wall of the leer and is set in the narrow vertical vclearance space between the disk 9 and the' knock-off arm 103.` This arm is tightly fitted to the top `of the knock-olf rocker-shaft104 which is rotatably enclosed in .the hollow shaft 113 carrying the disk. At the bottom of the. knock-olf shaft 104 is the tightly `{itt-ed cam lever 105 carrying at its swinging end the roller 106. This roller bears upon the wearing face ofthe knock-olf cam 107 which is tightly fitted to the shaft 95 and is so designed that the knock-off arm will be actuated in time periods and directions corresponding to those of the transferdevice, 112, and corresponding to the time required for the cross-conveyor to advance one pitch length, these time periods' being in exact \relation to the rate of production of the pieces of, Ware. The. Icam 107 is shown'A with'four actuating projections arrangedin quadrant spacing but a greater or less number of these may be used provided that the speed of the intermediate shaft 95 is lvaried accordingly. The angular travel ofthe knockvoff arm '103 is just suilicient to pusheach swinging end of the armis concaved 'so that each piece of ware will beheldto a circular path with constant radius on the plate 102. After the ware has been pushed off of the plate the receding stroke. of the arm'103 1s caused by the reaction of the Aspring 108, attached at .one end to the cam lever. 105 and at the other end to the leer structure.

Inthe construction of this leer and automatic feeder the plates for supporting and reinforcing the masonry, as well as those serving for supports for the moving memtogether thus securing permanency of alignment and avoiding Icracks in the masonry due to the expansionand. contraction. The drawings show a leer where the ware enters at the left hand side but it is obvious that certain parts maybe reversed thusconstituting a right hand leer Without in any way affecting the operation as herein describe As shown in Fig. 2 the. diskl 9 and the s rocket wheels 39, 40 have a clockwise rotation and the cam shaft 80 runs counterclockwise as seen in Fig. 1.

The function of the transfer device, 112

is to grip each piece of ware as it is ready` for delivery from the mold and carry it 'toy the rotating disk at intervals of time above 125 described. The position of thetransfer arm when taking ware from the mold-11s shown by the broken line between ghe centers of the mold 8 and the transfer base, 112. From this positiony it swings in a horizontal Plane im,v

in a circumferential-p'athto the platt 102 where the ware is released. When the piece of ware is in position for delivery from the molds it is gripped by suitable tongs on the transfer arm. In order to secu-re free release at the receiving position at the leer each piece of ware must bel set upon a stationary receptacle. and this is provided each pieceA may be deflected tothe disk 9 inthe device for transferring the ware fromby they plate 102. It is evident that other devices for transferring ware from the mold to the leer may be employed, for instance,

a well known manner from an intermediate chain conveyor properly adapted therefor and properly heated. It is understood that the mold to the disk 9 must effect the transfer in a space of time not to exceed the time limit as herein set forth, such time limit being set at from one to three seconds, ac cording to the size `and wall thickness of the pieces of ware.

In operation the piece of ware, after having been pushed fromthe plate 102 to the disk 9, is carried by the disk until it comes in contact with a pair of the chain attachments 4 5, 45. From this point the bottle or other article is carried by the said attachments against thefrictional resistance and across the face of the diskto the fixed-plate 46. Duringthis time the bottle. will be held a ainst thechain by its friction with the disk which is almost directly across the path of the chain at the junction between the disk andthe fixed plate, at which point' the surface of the plate Iis slightly lower than that ofthe disk. The bottle is held in place Y between the chain attachments while `on the plate 46 by the jointed curved guidl 109, 109". The plate is parallel at its junction with the disk but from this point is slightly twisted so that at its junction with the carrier-plate47, which is slightly lower on the side nearest the chain, the top surfaces of the-two members will be in line.

After being carriedv by the cha-in attachments to the carrier-plate the bottles remain between the attachments and close to the chain links by the 'action of gravity due to the slightinclination of the plate towards the chain, and, asthe attachments -45 are directly over and at a considerable dista ce above the attachments 45e, thelatter being close to the plate, the posslbility of the bottles toppling over sideways is avoided.- The chain 43 is so speeded that it advances exactly one pitch length in the time corresponding to the rate of' production, and the ,joint actions of the transfer device, the knockofi1 .arm 103 and the disk 9 are. so timed that each piece of ware will come into contact with the leading chain attachment over the disk while it is in about the position shown i in Fig. 2. At the moment when the crossrow is completed, with. a 'bottle'in each of the pockets between the chain attachments overv .the carrier-plate and the chain in the position shownin Fig. 2, `the'projection on lthe face of cam 77 engages V'the roller 83 and through the rocker-arms 81, 75 and the links 78, 74, 49, 50, .the carrier-levers 48, the shoes space 67,1 Fig. 4, the combined frictional resistance between the lslides and `shoes andl the tension of the springs- 60 being less'than the frictional resistance between the shoes and the plate 58 upon which they slide. v At the beginning of this period of angular advance of the cams all'of the carriermembers are in the' positions shown i'nfFigures 1 and 4, with the roller 83 at the point a, the

rollerv 84 at-the oint va1 and theroller87 at the point as in ig.V 5. yThe surface of tlie cam 79 between the points a? and b3 is cylindrical and concentric w'ththe shaft sothat there is no kaction in the rcller, 87 and its connections'duri'ng this period of camI .ad- Vance. always :be held in contact with the 4cana 79 on account of the upward pull on the arm 86 due to the unbalancedv condition of the carrier-levers 48.

It is evident that the roller 87 will The working surfaces on cam 77 from i the points b to o' and on cam 78 .from b1 to o1,

Fig.. 5,'are cylindrical and concentric with their shaft so that there is no action Lin the rocker-arms 81, 82 and their connected parts during this `period of angular advance, but

at the beginning of this period ,the roller 87 descends from lthe point bs tot*s raising the rocker-arm86, the connecting-rod. 89, the

rockerarm 91Nand the rollers 5-1 thus allowing the heavier inner ends of the fcarrier-llevers-48' and the carrier-plate with the completed row of bottles' to descend to the positions shown in Fig. 4c. Theworking surface ofthe cam 77 between-the points@ and d is depressed towards the center a distance equal to half the radial increase between the points a andl b, and the surface-onthe cam 78 correspondingly rises an equal distance from the point o1 to d1; The surface of the cam 79 is'cylindrial 4'and concentric with the shaftffrom the points c to d", consequently there 1s no action in the rocker-arms85, 86 and theirconnections during-'this period of cam advance.f l

During the angular advance-of the cams between the points c to d, 01 to d1, o? to da, it will be seen that the rocker-arm 82 will be driven- `from and the arm 81 towardsthe 1 center ofthe cams one half their full stroke and that the connected arm 75 and links 7 3 will have made a half stroke in recession.

-As there is .a certain and `considerable surfaces and pivots 70, it willbe seen that' the cam action from the points c to d, c1 to d1.

causes the carrier-levers and platev to recede Vtheir full original stroke while-the shoes yremain stationary and the slides and riderf plate recede a very short distance,`equal to the length of the space 67. v At the end of the above describedhalf stroke in recession,

with the cam rollers in the positions d, d1, d3,

the carrier combination will be in the posi' tion shown in Fig. 41 and the row of bottlesv will have been' deposited upright on the main conveyor 4. sAt this juncture, during therecession of the carrier-plate, the row `of bottles is held from following it due to 'their friction therewith, by the edge of the 'rider-plate' which cycle is stationary.

Betweerr the points d and during 'this part' of the e on cam 77 and between d1 and e1l on cam 78 the surfacesL are cylindrical and .concentric withthe shaft so that there is no action in the rockerarms 81, 82, 85 nd ,their connections during this period of angular advance. From the point d3 -to' c3 on cam 79 the roller 8 7 is driven back to its original position, `as -at 13,5, and the rocker-arms 52, 53 are depressed causing the inner ends of the carrier-levers and the carrier-plate to rise to their original positions. Between the points e1 and a2 on cani 78 the roller 84 is driven to its original position, as :at al, and between the pomts c and a1 on cam 77 the roller 83 1 descends to its original position, as at a,

thus completing their cycles of operation.

' During this 'period the rocker-arms 81, 82,

75 and the links 7 3, 74 recede the last half of their original stroke causing the shoes and on to the rider-plate "during the first part` of the cycle, aredeposited in their regular positions on the carrier-plate and continue their advance thereon. v

The radius of the cam 7 9'lat the point e3 is slightly less than at a4 so that at e the carrier-plate hasvnot quite reached its highest point, as seen in Flg. 46. But at a* the radius has gradually increased 'to that of the point a? so that at the completi-on of the cycle the carrier-plate will be in the position to'receive the row of ware, as seen in Fig. 4a.

The slightly lowered position of the carrier plate as in Fig. '4 is provided for so that therider-plate 'may not beraised by the carrier-plate at this part of the cycle, which .raising would impede the progress of the incoming ware from the fixed plate.

Referring to Feig, 5 itis evident that the angle between radial lines passing through the points a and b must equal the angle between radial lines passing through the points al and b1 as Well as between L3 and b3,

which may be termed homologous cam sectors, and that this is true also for each of the other homologous` sectors. The angular measurements of each cam sector arepredetermined to correspond to the selected time Ofdurationo'f the respective cam actions and it is apparent that when the arms 81, 82 are in act-ion the arm 85 is non-active and viceversa. The three cams must be in fixed angular relations to one another, as

in Fig. 5, so that each action will begin andv end at the, proper time. The faces of the camsare cylindrical and concentric with their shaft from the points at which each cycle of operation ends until the beginning of the next cycle so that the cam operated members are 'at rest. during this period o time. v f

Comparing Figures 4a. to 4", inclusive, it is apparent that the rider-plate 55 is in the same position and inclination relative to thel chain attachments in Figures 4b to 49, inclusive, as the exposed art of the carrier-plate 47 was at the beginning of the cam actions as in Fig.`4, and that the bottles carried by the chain attachments along and onthe rider-plate during the period of Cam actions lwill remain thereon until the completion of the cycles as represented by the action from points e `to al, at which time the partial row of bottles on the rider-plate will drop tolthe carrierplate. 79 need not necessarily be exactly coincident with those of the other cams theangles between the various points on cam' 79 may be varied somewhat, as for instance the carrierplate may be slightly lowered while it is advancing from the points 'a to L. The time duration of each cam action is preferably about half that ofthe rate of production of the ware so that the advance of the carrier-plate into the leer chamber, as from Fig. 4 to 4b, takes/place in the time and space As the resultant actions from the cam interval between the bottles, thus avoiding interferences.

Both the carrier and rider-plates are made of thin metal in order to avoid the tendency of the bottles to tip forward, at the time when they are droppedfrom the riderto the carrier-plate and from the latter to the main conveyor 4v as above described.

The operation. of the stabilizer device will be understood by reference to Figures 1 and 4a to 4b, inclusive. At the beginning of the cam action, as represented by Figs. 4c to 4d, the4 slides 56 are 4drawn backward a 'short distance on the shoes as `above described.y This backward movement swings- 'the arms 61 and L-sh'aped 'holder-bar 64 upthen advances, with the parts in relatively fixed positions, to the position Fig. 4", with the holder-bar still incontact with. the bottles. Whenthc 'holder-bar and its connected parts 56,57 recede to their original positions as represented by the cam action Lfrom e to al, Fig. 5, and from Figs. 4e t-o 4a,

the vertical leg of the holder-bar clears the lowered row of bottles on the main conveyor and the'incoming row is prevented from tipping forward from any cause by the said vertical leg. When suchv articles 'as tumblers, wide mouth bottles or other articles of medium stability` are being annealed the `stabilizer arms and holder-bar may be removed if desirable, without affecting the oppration of the other parts of the leer, in w ich case, the slides and shoes may be rigidly attached to one another, constituting single member. j y v The motor 5 is so geared to the main-conveyor drive shaft that the conveyor travels a distance-equalto the largest diameter of the pieces of' ware being annealed, plus a predetermined amount of clearance, in the interval of time corresponding to one revo-4 lution of the cam shaft 80. In order to vary the speed of the main-conveyor to suit the rate of production and size of the ware the motor is provided with any one of the well known speed regulators.'

yIn case "that the Ware should accidentallyclog while adjacent to the sprocketwheel 4 0. the outward pressure will force .open the hinged wall section 21 .carrying the curved guide 109b and the ware will be ejected' throughJ the opening and upon the table 58 -until the .fault is corrected by the attendant.
